| titleOfInvention | Kitchen oil smoke concentration detection method based on image processing |
| abstract | An image processing unit processes initial images of front and back frames collected by an imaging device as a basis, wherein the initial images are gray-scale images, and the method comprises the following steps: (1) carrying out frame difference processing on the acquired initial image to obtain a frame difference image; (2) denoising the frame difference image in an open operation mode to obtain a denoised image; (3) carrying out edge detection on the denoised image, and marking a motion area as an initial region of interest; (4) carrying out gray average value calculation and area smoothness calculation on the initial region of interest, taking the region which meets the requirements of gray average value and smoothness as the next region of interest, and taking other regions as interference elimination; (5) and (4) respectively carrying out gray histogram statistics on the interested areas extracted in the step (4), and dividing the oil smoke concentration levels according to the statistical results. The invention can realize non-contact real-time detection of the oil smoke concentration and has the advantages of high accuracy, real-time property and the like. |
